Girls’ education advocate Malala Yousafzai turned 20 on Wednesday and the birthday wishes are pouring in on Twitter from the likes of Michelle Obama and Chelsea Clinton.

“Happy Birthday, @Malala! Your courage inspires us all to keep fighting for girls everywhere to get the education they deserve,” the former first lady tweeted Wednesday evening.

Clinton kept it simple with a “Happy birthday, Malala,” while former Vice President Joe Biden’s charitable organization, the Biden Foundation, tweeted: “Happy birthday, @Malala! We’re thankful for your remarkable spirit and powerful work in the fight for girls’ education around the world.”

Political figures weren’t the only ones to give birthday shoutouts to Yousafzai, a global education activist who at 17 became the youngest person to ever win a Nobel Peace Prize.

Once Upon a Time actress Lana Parrilla and actor Matthew Modine also honored Yousafzai with some kind words on her birthday.

Yousafzai gained international attention as a teenage schoolgirl after she spoke out against the Taliban banning girls from attending school in her community in Pakistan. Later, in 2012, a 15-year-old Yousafzai was shot in the head by the Taliban while she was riding a bus home from school.

Since recovering, she has opened a school for Syrian refugee girls and founded the multi-million dollar Malala Fund fighting for every girl’s right to 12 years of free, safe, quality education.

To commemorate graduating from high school last week, Yousafzai joined Twitter and called on her followers to join her in her fight for girls’ rights.
